and separable Vehicle-Wheel Rims, of

which the following isa specification, refei once being bad to the accmnpanying draw h1g2, forming a part thereof.

y invention relates to improvements in wheel rims, and has for its object the pm; is in of a simple, strong and eiiicient rim, which shall also be easily :manufactored and read ily handled 'by the user,

In my improved construction, i1 i availed of the force exerted by the inflate tire, for aiding in retaining the rim upon the "vehicle Wheel. Furthermore, l have provided a rim comprising simply a roiled, annular base-portion, transversely split and suitably shaped, to receive two rings or flange-members, adapted to accommodate tires either of'the clencher or non-clencher types.

Preferably the base portion provided with a suitable device for expanding and contracting the same, while an 'nterior channel isafi'orded for acconnnodating the folly-band of the wheel.

Further details of construction may best be explainedby referring to the accordpanying drawings, whe'rein:---

Figure 1. is a combined sectional and fragmentary isometric projection of a fellyrim and tire embodying my improvements;

Fig. 2, is a fragmentary side view, partially broken away, showingthe rim, screwmechanism and felly;

Fig. 3. is asectional view of the rim, illustrating a minor modification;

Fig. 4. 'is a fragmentary view of the over lapped ends of the baseportion;

Fig. L is a transverse sectional view of an additional modified type of rim mounted upon its folly, and

Fig. 6;. is a fragmentary side view illusadditional modification.

n Throughout the several figures of the drawings, I have employed the same character of, reference to indicate similar parts. 'From an inspection of the drawings, it will be apparent that my improved rim, is of the simplest construction, comprising it does, but three principal members. Two of these are merely reversible z-atainingrings, which are adapted to hold the tire in posi tion, when the rim is mounted upon the wheel. The third member, or base-portion of the rim, is of peculiar construction and ali'ords a central interior retaining channel which is clamped closely about the 'fellyband of the wheel, while two lateral channels, either exteriorly'or interiorly disposed,

and whose walls are cohici'dentWvith the former, are adapted to accommodate and permit the insertion and removal of said rings, when the rim is demounted from the Wheel.

Referring to Fig. 1, it is seen that the i'iYl a ot-the wheel provided with a metai tellyband 5, which its in the base portion a o? the rim. This member 0 is rolled from sheet metal, to provide a split annulus, as best shown in Fig. the endsthereof lwing'slightly beveled and united by means of lugs 7c'-/e' and a screw device 6. By means oi said screw the rimonember 6 may be caused to expand or contract, for the purpose of slipping it, together with the at tached tire, upon and off from the telly of the wheel; inasmuch as said r m-member when e sanded, is of sligl'itly larger circumference than the folly-band.

Two continuous annular retaining-rings f are assembled upon said rim-member, as

below described, for retaining the tire g in place upon the wheel. In order to accommodate the flanged rings, and the felly-band, respectively, the base portion 0 is peculiarly rolled trnafi'ord two exterior channels a.

which normally are of less circumference than the retaining rings f, While continuous over-turned lateral flanges 0 are provided for the normal retention of said rings within their respective channels formed in said base portion 0.

As indicated in Figs. 1 and 3, these re The overturned flanges c are so propor tioned as to engage the bases of the rings f and form 'What I may term a clencher flange" for securely holding said rings and tire firmly upon the base-portion and sup;

porting wheel. In the modified construction, of Fig. 3 these annular flanges are shown to be of equal height, while the rings are reversed in position to receive a Dunlop style of tire.

In Fig. 1. however, the right hand flange 0 has a slight upwardly extending flange c to form an additiona'l abutment for the in wardly positioned ring; as mounted upon the wheel.

In Fig. 5. I have. shown a. modified type of rim exhibiting the same rinciples of construction and o 'ieration. These structural differences, however coniprise a base-portion It, transversely split and equipped with screwanechanism, as bet'orc explained, which however, has the. respective channels it It", both interiorly positioned within the rim, but otherwise said member is constructed in the manner above described. The continuous retaining rings Z are cor-- respondingly modified to ati'ord interiorly engaging grooves a" and flanges Z, for fit ting within said channeled base port-ion.

Fig; (3 presents a slight modification, which is found in the inserted section j, bridging the separated ends of the base portion 0 of the rim. The removal of said 1nem-' ber j, after the rim has been de-inoul'ited from the wheel, permits the ends to be brought together, in order to remove the' outer ring f and tire The operation of my improved demountable rim may now be explained. The annular base-portion is first contracted in circiunference, by overlapping the severed, but normally connected ends, as indicated in Fig. 4. .(..18 of the retaining rings then slipped into its channel, the tire 5 is placed upon the rim and the second or outer retaining, ring f is placed in position within its channel. The telly is longitudinally slotted to amronin'iodate the screw-mechanism; said slot being reinforced at c and provided with a pivoted cover plate at, which is shown partially broken away in Fig. 2.

The base-portion is explained by turning screw to separate the split end portions as it reacts against the lugs l':- in. The valve-stem (imlicated by dotted lines, Fig. 2,) and the screw device a, may now be inserted within the spaces provided therefor in the slotted and bored telly; the same being either laterally or longitudinally displaced. Then the rim and tire are mounted upon the wheel, so that the channel 0' registers with the folly band. The screw is then turned in the opposite direction to decrease the circumtmence of the base portion of the rim, to the extent desired. Thus.said

screw in reacts upon the left hand via ll ofthe slotted telly, drawing the tapped lug Z1 and its attached end of the base-portuni 0, toward the right, while lug A;", being forced against the right hand wall of the slot, anchors the other end of said base-portion and the ends, accordingly, are drawn together. Moreover, the rim is held against circumferential displacement, by these means.

In view of the construction of parts above set forth, the inflated tire acts circumfei= entially against the transversely split ba eportion and materially assists in seatingit upon the telly-band of the wheel. Accordingly, my improved dernountable and separable rim is seen to comprise two rings of such circumference to accommodate and hold. securely in position, the annular retaming members of a tire. These are eta-- ploycd in conjunction. with a base-portion of variable circumference, which may be contracted to receive the rings and tire, then expanded to fit over the wheel folly and finally contracted by means of the screw and air pressure of the'tire, sutliciently to hold the wheel, rim and tire in fixed relation. The wheel, of course, affords a rigid abutment at all points for preventing buc; kling or undue contraction of .thc basefpotion of said rim.

Having now described the preferredembodiments of my invention, I claim as new,-

and desire to secure by Letters Patent, the following 1. Ida device of the class described, the
